Specification of Letters Patent.

F o all whom it may concern:

lie it known that we, Emmi-z J. Rnssnnii a'ii l lannis V. Dye, citizens of the United States, residing at St. Louis, State of Mis-- sour-h and East St. Louis, in the county of St. Clair and State of Illinois, respectively, have invented certain new and useful linprovements in Grain-Car Doors, of which the followingis a'specilication.

Qur invention relates to grain car doors.

The objects of the invention are to provide a sectional grain door, the sections of which are capable ofbeingoperated individ ually from the exterior of the car; to form the door in two upper and two lower seelions, each pair having a common operating rod adapted to he successively geared to said sections; to provide the adjacent edges of one pair of doors with a traveling track adapted to be moved across the doorway and into alinement with a fixed track, on which the adjacent edges of the otherpan of doors travel; tosofconstruct the said doors that they will-lieflush with the lining of the interior of the ear and not inter' ere inany way" with the operation of'the usual outer doors, and to provide a sectional door of the character described which will prevent any waste of grain, be simple in constructionand safe and easy in operation. These ob ects we attain by the mechanism shown in the accompanying drawing, in which- Figure l is a side elevat on of our improved grain car door, from the outside of the car with the stndding and sill removed to better show the construction. a horizontal section on line 2--2 Fig. 1, showing-the framingof the car. Fig.3 is a vertical section on line 3 -23, Fig. 1. Fig. i is a detail View of one of the split collars on the lower end of one of the vertical operating shafts. Fig. 5, a detail sectional view of: one of the horizontal brackets and Fig. (l is a detail view of the meeting ends otthe guide rails. 7 is a section through the sliding rail or track D on line '?7 Fig; 1. Fig. 8 is a scetioi'i on. line i, S Fig. .1.

A, lesignales the side of a grain or freight It, its door iranie o, the inner lining 3" mg. 2 is passing thcrethreuglu ot the door frai'ne AC, are pocket plates B, 5, which are secured in place by screws Z), and 10 about flush with the lining (1, of the ear; Behind the plates ll, next to the inner ;sides of the studding of lies the sectional door which when open is concealed by the iplates B. This door is in four sections C, U, C C the upper and lower sections C, C, being at one side of the doorway behind plate B, and the other two sections C being at the opposite side of the doorway {behind the plate B.

D is fixed track behind the plate B, and having its upper and lower edges groo'vedto form ways in which slide the adjacent edges of the door sections Catt,

door sections (1, C;

while at the opposite sides of-tlie doorway works a loose track or guide rail 1), which also has grooves in its upper and lower \Vithin the grooves oi the two rails or tracks 13,1), are mounted anii-friet on rollers (Z, which render the sliding fthe doors much easier.

The sliding rail or track D. is provided edges to receive the adjacent edges of the ,on its upper edge between its ends and lit its inner end with upstanding lugs (Z, (P, in .the path of a pin (1*, projecting from the ;side 'of the door section (7, at its lower inner corner, as shown in Fig. 1, so that when the .door section 0, is moved across the doorway ithe lug d, and move the rail or track 1) ihand entirely across the doorway t e-the middle thereof the pin (Z will engage with 1:. Annthis on rail 1),-is moved b until its outer end registers with the end of the'fixed .rai-l- I) see dotted lines Fig. 1; the meeting ends of the rails or tracks lilting one within the other as shown at d" Fig. 6.

E, designates a' track on the'upper side of.

the ear sill grooved to receive the lower edges of the two lower door sections C, Q, and this track is provided in its groove with anti-friction rollers (1 carried by brackets E. The brackets E are let into the floor, of the. car and are riveted to the plate I) and help brace it against strains.

The door sections are operated as follows: F, designate. two vertical shafts proends of the shafts F, F, are provided with i vidccl. with upper and lower oppositely fan ing bevel gears t G, and theseshafts are 105 other pair of door sections andseparate and independent thereof, means for actuating thesliding rail from a door section, and an operating mechanism for each pair of door sections, operable from the. exterior 'ofthe car;

8. In a car a grain door mechanism com prising, pocket plates at opposite sides of, the doorway, pairs of sliding doors working behind said pocket plates an operating device, a fixed trackfor the adjacent edges of one pair of door sections, a movable track between the other pair of door sections separate and independent thereof and of a'length to cross the doorway, means on the one of the latter'doorsections to actuate said movable track, individual actuators for the door sections and main actuators movable alternately into and out ofgear with said individual actuators.

9. In a car, agrain door mechanism comprising, a pair of horizontally sliding door Sections at each side of the doorway, and a horizontal screw shaft operatively conoperatively connected and each having I .to mesh with the screw shaft gears,

nected with the respective door sections and each having a bevel gear, of vertically movable shafts having external-opera'ting means and each having a pair of oppositely facing bevel gears adapted to be moved by the shaftssuccessively into mesh with the gears on the screw shafts. I a

10. In a car, a grain door mechanism comprising, a pair of horizontally sliding door sections at each side of the doorway, a fixed guide for the adjacent. edges of one pair of door sections,

other pair of door sections, ascrew shaft with every door section, gears on said screw shafts, two vertioally sliding shafts having gears adaptedspr ngs to raise the shafts, a hand-wheel vertical shaft and split collars on thelower ends of the vertical shafts between the hand- .wheels and the lower sides of the car sills to depress the shafts against the action of their springs.
